SPECIFICATION forming part of Letters Patent No. 608,584, dated August 9, 1898. Application filed June 5,1895. Renewed October 23,1897. Serial No. 656,193. (No model.) I

To all whomjt nay concern:

Be it known that I, CHARLES D; DE FOREST, a citizen of the United States, residing at Pittsburg, inthe county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Collar and Socket Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in machines for making sleeves for pipes and the like.

The objectof the invention is to construct a machine of the 'above-referred-to class that will be strong, durable, and effectual in its operation. v

The invention has for its further object the provision of novel means whereby the mechanism may be easily andreadily adjusted to manufacture different sizes of sleeves.

The invention consists in the "novel construction, combination, and arrangement of parts to be hereinafter more particularly described, and specifically pointed out in the claims. I

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification and Wherein like figures of reference indicate similar parts throughout the several views, in which.

Figure 1 is a front elevation of my improved machine for making sleeves. Fig. 2 is a side elevation of the movable bearing. Fig. 3 is a front view of the same. Fig. 4 is a vertical sectional view. Fig'. 5 is a detail side View of the connection between the piston and horizontal shaft. Fig. 6 is a plan view of the same. Fig. 7 is a modification of the arrangement of the rolls. Fig. 8 is a detail view of the levers and valves.

In the drawings, 1 indicates the pulley communicating power; to the pulley 2 by means of a belt 3, rotating a horizontalshaft 4, carrying on its end a plunger 5. Said shaft is mounted in bearings 6, 7, and 8 and carries The reference figure 10 represents the steam-cylinder, provided with an ordinary piston-head and piston 11, coupled at 12 to a coupling 13, attached to the horizontal shaft 14, the former being mounted in a stationary bearing 15 and the latter in a movable bearing 16, operating in' guides 17. Atthe end the horizontal shaft is provided with a shaper 18. The "motion of the, piston-rod is reversed by means of a series of levers19 19, opening and closing the outlet-valves 20 and 21, the inlet-valve being indicated by the referencefigure 22, and 22 indicates the reversingvalve. The upright standards 23 23 serve as bearings for the shaft 24, carrying the roll 24, the latter being adjustable vertically by 1116311 15 of lever-pawls 25 25 and a connectingrod 26 of the miter-gear or ratchet wheels 27, carrying vertical screw-threaded shafts 28 28, operating the bearing-blocks of the shaft 24. By this means the roll 24 may be raised and lowered.

The'operation of the machine is as follows: The'hotjmetal is placed between the shaper and plunger and the valve set so as to drive the piston-rod carrying the shaper toward the plunger, and the machine is set into opera tion and forms the sleeve or socket. Anysized shaper and plunger may be substituted and the roll set accordingly.

It will seen that thegeneral characteristics of the mechanism consist in having a supporting or forming "roll 18, which is adapted to, support the entire body of the welding metal and is adapted to be moved longitudinally without stopping the machine and to carry the welded metal bodily with' it as it moves longitudinally; secondly, in having a pressing or welding roll opposite to the normally-operative position of the shaping or forming roll, and, thirdly, in having a strip ping part which shall discharge the metal from the shaping and forming roll as the latter is moving longitudinally. 7 V

There can be numerous modifications of the parts to attain the ends of those referred to. In the present constructionone of the flanges on the pressing or weldingfi oll serves as a stripper, the me'talbeing' fitted andpressed into the groove or cavity in the periphery of said roll, so that the flange prevents the movement of the latter with the other roll.

The forming or shaping roll 18 (in that it supports the entire body of the welded metal) differs from those heretofore suggested for this purpose, which were made in two disk-like halves which were separable in the midway vertical plane for the purpose of holding a narrow ring welded thereon to drop immediately downward when the two halves were separated. The present mechanism is for the treating of relatively long sections of tubing, thimbles, couplings, &c., and hence a firm support is requisite at the central part of the metal longitudinally, and to attain this a support continues through the thimble or coupling, and this requires the presence of a stripper which can remove the metal from the forming-roll as it is being moved bodily longitudinally with said roll. When the two parts of the forming or shaping device are separable at the midway plane of the press ing or welding roll, a bead or fin is apt to be formed on the metal at the middle of its in-- nor surface, which requires subsequent turning or machine-work to permit its use as coupler-pin tubing, and this is avoided by having the supporting-surface continuous and providing a stripper for removing the metal from the roll.

It will be seen that various changes may be made in the details of construction of my device without dcparting from the general spirit of the same.

llavin g fully described my invention, what I claim as new, and desire to soon re by Letters Patent, is-- 1. In a machine for making sleeves for pipes, the combination of the steam-cylinder and its piston, the endwise-movable shaft coupled to said piston and provided with a shaper, the reversing valve mechanism arranged in connection with said steam cylinder and adapted to provide for the reversing of the movement of said shaft, with its shaper, the rotatable plunger opposed to said shaper and the finishing-roll arranged eontiguously to and above said longitudinally-movable shaper and rotatable plunger, substantially as set forth.

In a machine for making sleeves for pipes, the combination of the cylinder and its piston, the endwise-movable shaft provided with a shaper and coupled to said piston, the reversing valve mechanism comprising a series of valves arranged in pipes connecting with the ends of said cylinder and in a pipe connecting with the aforesaid pipes and interacting levers between said valves, a rotary plunger opposed to said shaper, and a finishin g-roll arranged contiguously to said shaper and plunger, substantially as specified.

3. In a machine for making sleeves for pipes, the combination of the cylinder and its piston, the endwise-movable shaft coupled to said piston and provided with a shaper, the reversingmechanism forsaid piston and shaft with its shaper, a rotary plunger opposed to said shaper, the finishing-roll arranged in eoasse juxtaposition with said shaper and plunger, and the mechanism for effecting the vertical adjustment of said finishing-roll comprising the vertical screw-threaded shafts engaging the bearings of the shaft carrying said finishing-roll, and provided with the miter or ratchet wheels and the connected lever-pawls adapted to engage said ratchet-wheels, substantially as described.

In a device of the characterdescribed, a series of two or more rotatable rolls, means for rotating one or more of them, means for imparting to one of said rolls a longitudinal movement independently of the rotation-cans ing devices, and a stripper, substantially as set forth.

5. In a device of the characterdescribed, a series of two or more rotatable rolls, means for rotating one or more thereof, means for imparting to one of said rolls a longitudinal movement independently of the rotation-cans ing devices, and a stripper extending around and concentric with one of the rolls, for discharging the welded metal, sul'istantially as forth.

0. In a mechanism of the character described, the combination of a pressing or welding roll, a holding or forming roll, a rotary abutment contacting with the holding or forming roll to relieve it of thrust, and means for imparting longitudinal motion to the holding or forming roll, substantially as set forth.

7. I11 a mechanism of the character described, the combination of a pressing or welding roll having a groove or flanges, and aholding or forming roll having one or more flanges, and means for moving the holding or forming roll longitudinally, one of the aforesaid flanges around the rolls bein adapted to serve as a stripper, substantially as set forth.

8. In a mechanism of the character described, the combination of a longitudinal. movable holding or forming roll having radially-exten ding flanges and a metal-supporting surface extending continuously from one flan go to the other, whereby said roll is adapted to carry the welded metal bodily when it moves longitudinally, an opposing pressing or welding roll, and a stripper for removing the welded metal from the carryirig-surface on the longitudinally-moving roll, substantially as set forth.

9. In a machine of the class described, the combination of a welding-roll, a supportingroll arranged below the welding-roll, and having a continuous supporting-surfaee extending from one side of the welding-roll to the opposite side thereof, and means for moving longitudinally the last said roll for positively forcing the welded metal therefrom, substantially as set forth.

10. In a machine of the character described, the combination of a metal-supporting roll. comprising two sections, each provided with an annular flange or abutment,and one adapted to have its body portion completely surrounded by the body portion of the other seethe flanges around the supporting-roll longitudinally of the axis thereof, and means for positively forcing the metal from said sup- 15 porting-roll, substantially as set forth.

In testimony that I claim the foregoing I hereunto affix my signature this 27th day of December, AFD. 1894.
